Modified Files:
	src/lib/libc/gen: getgrent.c
Log Message:
change getgrent() backends so that a flag (per source) is set once the
source has been exhausted. this allows getgrent() across multiple
sources (e.g, ``group: files nis'') to work correctly. the flags are
reset in setgrent()/endgrent().

(as per similar change in getpwent.c rev 1.42)

XXX: this change means that code that uses getgrent() to obtain a list
of groups will have to do duplicate suppression... getgrouplist()
springs to mind; i'm about to modify that
